Napa Social Clubs / Activities

What are folks' favorite social activities to do here in Napa? Looking for suggestions for classes, clubs, game nights, non-competitive activities, crafts, etc. Kudos for recommendations with a low barrier to entry!

EDIT: also, extra appreciative of things that don’t require a pair (for example, I’d really like to go to trivia night, but don’t have anyone to go with and feel weird just walking in and asking a team if I can join!)
